Abstract

Eine Schneidvorrichtung zur Verwendung in einem Unterwassergranulator (1), welcher einen Düsenkopf (3) mit einer um eine Mittelachse (M) des Düsenkopfs rotationssymmetrische, ins­ besondere konische Schneidfläche (31) aufweist, in welcher Düsenöffnungen (32) ausgebildet sind, weist eine Antriebswelle (6) und zumindest einen Schneidkopf (5) mit einer Vielzahl von Schneidmessem (9) zum Abschlagen von aus Düsenöffnungen (32) eines Düsenkopfs (3) aus­ tretendem, strangförmig geformten, geschmolzenem Kunststoffmaterial in Form von Granulatkömem, auf, wobei der Schneidkopf (5) einen Mechanismus aufweist, mittels welchem durch Betätigen eines Betätigungselements (83) die Vielzahl von Schneidmessem (9) gleichzeitig relativ zur Schneidfläche (31) verstellt werden können in einer jeweiligen Bewegungsrichtung (B), die eine Bewegungskomponente in radialer Richtung senkrecht zur Mittelachse (M) und eine Bewegungskomponente in axialer Richtung parallel zur Mittelachse (M) beinhaltet. Die Bewe­gungsrichtung (B) ist bevorzugt eine Richtung einer Flächennormale auf die Schneidfläche (31) am Ort einer Schneidklinge (91) eines jeweiligen Schneidmessers (9).A cutting device for use in an underwater granulator (1), which has a nozzle head (3) with a cutting surface (31) that is rotationally symmetrical about a central axis (M) of the nozzle head, in particular conical, in which nozzle openings (32) are formed, has a drive shaft (6) and at least one cutting head (5) with a large number of cutting blades (9) for knocking off molten plastic material in the form of granulate grains, which is formed in the form of a strand and is emerging from the nozzle openings (32) of a nozzle head (3), the cutting head ( 5) has a mechanism by means of which, by actuating an actuating element (83), the plurality of cutting knives (9) can be adjusted simultaneously relative to the cutting surface (31) in a respective direction of movement (B), which has a movement component in the radial direction perpendicular to the central axis ( M) and a movement component in the axial direction parallel to the central axis (M). The direction of movement (B) is preferably a direction of a surface normal to the cutting surface (31) at the location of a cutting blade (91) of a respective cutting knife (9).
